Abstract
A holographic display module is incorporated into a machine with independently operating subsystems, and used to provide an indication of the status or location of the machine subsystems. In one embodiment, a xerographic copier incorporates a holographic display incorporating an outline of the machine. A liquid crystal panel is aligned with the holographic display and selectively addressed in conjunction with signals from the copier subsystems. An illumination subsystem is optimized to provide diffuse illumination of the display.
